[0033] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0034] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0035] Reference Figure 1 , Figure 2 As shown, the present invention discloses an ultra-thin flat connecting lock device, through which a plurality of frames are connected, specifically, including connecting components 20 respectively located on adjacent frames 10, and the connecting components 20 include a semicircular fixing seat 201 and a rotating seat 202; since the structures of the connecting components 20 are completely the same, in this embodiment, the structure of the connecting component 20 on one of the frames 10 is described in detail, wherein the frame 10 is square, and in order to achieve a stable connection between adjacent frames 10, two connecting components 20 are distributed on each side of the frame 10; refer to Figure 2 As shown, the fixing seat 201 is provided with a screw hole 2011 and a positioning column 2012, and correspondingly, the frame 10 is provided with a threaded hole 101 and a positioning hole 102, the positioning column 2012 on the fixing seat 201 is inserted into the positioning hole 102 to achieve positioning, and then the screws are locked into the screw holes 2011 and the threaded holes 101 to achieve the fixation of the fixing seat 201.

[0036] Combination Figure 3As shown, for the specific structure of the fixed seat 201 and the rotating seat 202, the present invention provides a specific embodiment, the fixed seat 201 and the rotating seat 202 are both semi-circular, the fixed seat 201 is provided with a first arc groove 2013 and a first arc boss 2014 in the shape of an arc, and the rotating seat 202 is provided with a second arc boss 2021 and a second arc groove 2022 in the shape of an arc, and the first arc groove 2013 is located on the inner side of the first arc boss 2014, and the second arc boss 2021 is located on the inner side of the second arc groove 2022; therefore, it can be understood that the first arc boss 2014, the first arc groove 2013, the second arc boss 2021, and the second arc groove 2022 are all semi-circular. The openings of the first arc groove 2013 and the second arc groove 2022 are both provided with guide ramps 203 to avoid jamming during the rotation of the rotating seat 202.

[0037] When the fixed seat 201 is fixedly mounted on the frame 10, the rotating seat 202 is located below the fixed seat 201, and the second arc boss 2021 of the rotating seat 202 is limited in the first arc groove 2013, and the first arc boss 2014 is limited in the second arc groove 2022; Figure 4 As shown, when the first frame 103 is connected to the second frame 104, the fixed seats 201 and the rotating seats 202 of the two sets of connecting components 20 are connected to each other, the two fixed seats 201 form a complete ring, and the two rotating seats 202 also form a complete ring; Figure 5 As shown, after the rotating seats 202 of the two sets of connecting components 20 rotate, in this solution, the rotating angle of the rotating seats 202 is 90°, that is, it rotates to the extreme position, wherein the two fixed seats 201 respectively limit the rotating seats 202 of the two sets of connecting components 20 to achieve the connection of adjacent frames 10, thereby completing the locking splicing of adjacent frames 10. At this time, the first arc groove 2013 simultaneously clamps the second arc boss 2021 of the two rotating seats 202 therein, so that the two rotating seats 202 cannot move up, down, left, and right relative to each other; similarly, the second arc groove 2022 simultaneously clamps the first arc boss 2014 of the two fixed seats 201 therein, so that the two fixed seats 201 cannot move up, down, left, and right relative to each other, thus achieving the locking between the two frames 10. At the same time, the cooperation between the second arc groove 2022 and the first arc boss 2014, and the first arc groove 2013 and the second arc boss 2021, prevents the two fixed seats 201 and the two rotating seats 202 from making relative movements in the front-rear direction.

[0038] Through the above connection method, when multiple adjacent frames 10 need to be spliced, such as Figure 5As shown, a specific embodiment of splicing four frames 10 is provided, including a first frame 103, a second frame 104, a third frame 105 and a fourth frame 106, so as to realize the splicing of multiple frames 10 to meet the requirements of the prior art for outdoor large-screen display. The ultra-thin flat connecting lock device of the present invention is used on a composite material frame 10 with high thickness requirements; it can ensure that the thickness of the product after using the device is ultra-thin, and can also ensure that the product can be easily and quickly spliced ​​and disassembled without tools.

[0039] For more details about the above embodiments, refer to Figure 3 As shown, a third arc boss 2023 is arranged on the outer side of the second arc groove 2022, and a rotating handle 2024 protruding outward is arranged on the outer side of the third arc boss 2023. By rotating the rotating handle 2024, the rotation of the rotating seat 202 is realized; further, an arc-shaped first limiting groove 2025 is arranged on one end of the inner wall of the third arc boss 2023, and a limiting notch is arranged on the other end of the inner wall of the third arc boss 2023, and the limiting notch is the second limiting groove 2026; a limiting boss 2015 is arranged at both ends of the fixed seat 201, and the two limiting bosses 2015 are respectively located in the first limiting groove 2025 and the second limiting groove 2026. The mutual cooperation of the limiting boss 2015 and the second limiting groove 2026 can ensure that the rotating seat 202 can rotate relative to the fixed seat 201 within a preset angle range after installation, and is always stuck under the fixed seat 201 and will not fall out.

[0040] In the above solution, the stop point of the first limiting groove 2025 is located in the middle of the third arc boss 2023, so the length of the first limiting groove 2025 is half of the third arc boss 2023; after the rotating seat 202 rotates, the limiting boss 2015 of the fixed seat 201 is located at the stop point of the first limiting groove 2025. Figure 4 The figure shows the state before the rotating seat 202 rotates. Figure 5 It is the state after the rotating seat 202 is rotated. It should be noted that the length of the first limiting groove 2025 can be adjusted according to actual conditions. For example, in another specific embodiment, the length of the first limiting groove 2025 is 3 / 4 of the first arc boss 2014, and the rotation angle of the rotating seat 202 is greater than 90°.

[0041] In the above embodiments, combined with Figure 3As shown, the fixing seat 201 is in the shape of a semicircular ring, and a semicircular notch is arranged at the center thereof. With this structure, a central arc boss 2016 in the shape of an arc is formed on the fixing seat 201, and the first arc groove 2013 is located between the first arc boss 2014 and the central arc boss 2016. When the fixing seat 201 is combined with the rotating seat 202, the second arc boss 2021 is located in the first arc groove 2013, so that the second arc boss 2021 is located between the first arc boss 2014 and the central arc boss 2016, so that the two are clamped, and the gap between the two can ensure that the two parts can slide relative to each other without being stuck, and can also ensure that the two parts are closely matched without obvious shaking. The above-mentioned screw holes 2011 pass through the central arc boss 2016 and are evenly distributed on the central arc boss 2016.

[0042] For the fixed seat 201 and the rotating seat 202, the present invention also provides a specific embodiment. On the basis of the above embodiment, in this embodiment, a limiting component for limiting the relative position of the fixed seat 201 and the rotating seat 202 is provided between the fixed seat 201 and the rotating seat 202. The initial state and the final state of the rotating seat 202 are positionally limited by the limiting component to improve the convenience of use and avoid loosening of the fixed seat 201 and the rotating seat 202 when no rotational force is applied.

[0043] Combination Figure 7 , Figure 8 As shown, for the above-mentioned limiting assembly, the present invention provides a specific embodiment, the limiting assembly includes an elastic limiting piece 301 and a third limiting groove 302, the elastic limiting piece 301 is arranged in the first arc groove, and the third limiting groove 302 is arranged on the second arc boss, and the fixing seat 201 and the rotating seat 202 are locked by the cooperation of the elastic limiting piece 301 and the third limiting groove 302. More specifically, the elastic limiting piece 301 and the third limiting groove 302 are respectively provided with two groups, and when the rotating seat 202 is in the original state and the state after rotation, the elastic limiting piece 301 is respectively inserted into the corresponding third limiting groove 302. If there is no external thrust at this time, the rotating seat 202 will be stuck and cannot rotate freely. The mutual cooperation between the limiting elastic limiting piece 301 and the two third limiting grooves 302 can ensure that when the rotating seat 202 is rotated clockwise to the maximum angle (the connecting component 20 is in a completely loosened state) and when the rotating seat 202 is rotated counterclockwise to the maximum angle (the connecting component 20 is in a completely locked state), there is an elastic limiting state, which can avoid vibration or other external factors that make the rotating seat 202 rotate freely and not conducive to installation and the risk of loosening after locking.

[0044] Combination Fig. 9 , Fig.10As shown, for the above-mentioned limiting assembly, the present invention also provides a specific embodiment, the limiting assembly includes a limiting ball plunger 303 and a limiting hole 304, the limiting ball plunger 303 is installed on the fixing seat 201, and the limiting hole 304 is located in the second arc groove 2022, through the cooperation between the limiting ball plunger 303 and the limiting hole 304, it can play a role Figure 7 , Figure 8 The effect in the illustrated embodiment is not described again in this embodiment.

[0045] The ultra-thin straight connection lock device of the present invention utilizes the circular arc boss and the circular arc groove on the fixed seat 201 and the rotating seat 202 to cooperate with each other to achieve locking and limiting, thereby ensuring that the thickness of the entire device is thin and meeting various use environments with strict dimensional requirements. The device has a simple structure, low manufacturing difficulty and cost, and is easy to operate and use without the need for auxiliary tools.

[0046] In addition, the present invention also provides a specific embodiment, in which a micro LED display screen is proposed, and the micro LED display screen includes the ultra-thin flat connection lock device described in any of the above embodiments.
